Why is the boiling point of cyclohexanol greater than that of cyclohexene?

Question

Why is the boiling point of cyclohexanol greater than that of cyclohexene?

Answer 1

Cyclohexene has no hyrdrogen bonding therefore has a lower boiling point.  

Answer 2

because cyclohexanol has Hydrogen Bonding between the O-H in the molecule  

Answer 3

Both molecule have the same cyclic structure, except that cyclohexanol has a hydroxy (-OH) group attached to it. The hydroxy group onthe cyclohexanol allows for Hydrogen Bonding. Hydrogen Bonding is the most strongest intermolecular force in bonding. The H-Bonding increases the boiling point. The H-Bonding occurs between the Hydrogen of one -OH group on one cyclohexanol to  the oxygen of another cyclohexanol. A general trend is that alcohols have higher boiling point than alkanes, due to the H-Bonding.
